Introduction

Ladies and gentlemen, welcome to this article where we'll be discussing an interesting HVAC issue that came up during a visit to the Ambassador David Freeman Plaza in Woodme, New York. Specifically, we'll be focusing on a rooftop unit that was experiencing heating problems. So sit back, relax, and let's dive right into the details.

The Ambassador David Freeman Plaza

Located just 500 feet away from our shop on Central Avenue, the Ambassador David Freeman Plaza is an area bustling with activity. It serves as a prime location for both residential and commercial spaces. It is in this vibrant setting that we encountered an HVAC problem that required our immediate Attention.

The Retail Location on Central Avenue

Situated on Broadway, our retail location in this busy plaza is equipped with two rooftop units. One of the units is a Ream unit, while the other is located at the rear of the building. These units are responsible for providing heating and cooling to the retail space below.

The Rooftop Units

The Ream Unit

Upon inspection, we noticed that the rooftop unit was emitting hot air. This indicated that the unit had Ignition, which was a positive sign. However, the main issue seemed to be with the blower not functioning properly.

The Heating Issue

As we investigated further, it became evident that the blower compartment was not where we initially thought it would be. It was discovered that the unit was equipped with a regular PSC motor instead. Although the blower spun freely, it was clear that we needed to replace the blower motor.

Blower Compartment Inspection

After removing the compartment cover, we stumbled upon an unexpected find. The Roll-out switch, which is designed to protect against overheating, had been moved. This was a clear indication that something was seriously wrong. Our instincts told us that there was a high probability of a failed heat exchanger.

Electrical Compartment Examination

To confirm our suspicions, we carefully opened the electrical compartment. And there it was, a capacitive smell of burning and cracks in the heat exchanger. The situation was grave, and immediate action needed to be taken to ensure the safety of the entire heating system.

The Failed Heat Exchanger

Signs of Failure

As we observed the cracked heat exchanger, it became apparent that this was the root cause of the heating issues. A failed heat exchanger poses a serious risk, as it can lead to the release of harmful gases into the building. This is a Scenario that should be avoided at all costs.

Capacitor Replacement

To address the blower motor issue, we replaced the faulty capacitor with an Amrad five microfarad single round capacitor. This allowed the blower to function properly and restored airflow within the system.

Confirming the Heat Exchanger Issue

To be thorough in our assessment, we removed the access panel to get a closer look at the heat exchanger. It was evident that the cracks were significant and warranted immediate attention. We promptly shut off power to the unit to prevent any further risks.

The Importance of Proper HVAC Maintenance

This incident highlights the importance of regular HVAC maintenance. By conducting routine inspections and addressing issues promptly, potential hazards can be prevented. It is crucial to keep HVAC systems in optimum condition to ensure the comfort and safety of all occupants.

The Crack in the Heat Exchanger

A crack in the heat exchanger can lead to serious consequences, such as the release of carbon monoxide into the building. This toxic gas is odorless, colorless, and tasteless, making it difficult to detect. Therefore, any signs of a cracked heat exchanger should be taken seriously and addressed immediately by a professional HVAC technician.

Taking Precautions

To safeguard against the risks associated with a failed heat exchanger, it is essential to install carbon monoxide detectors throughout the building. Regular inspections and maintenance by qualified professionals are also crucial in identifying and addressing potential issues before they escalate.

Conclusion

In this article, we explored a heating issue that occurred at the Ambassador David Freeman Plaza in Woodme, New York. We identified a failed heat exchanger as the root cause of the problem, emphasizing the importance of regular HVAC maintenance and prompt repairs. Remember, the safety and well-being of occupants should always be a top priority when dealing with HVAC systems. Stay vigilant, take necessary precautions, and ensure that your HVAC systems are in good working condition at all times.
